  1. 1. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Máté Károly Tóth; [2023]
    Nyckelord :Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

    Sammanfattning : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

  3. 2. Stock Splits' Impact on Liquidity Under Current Market Conditions

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Ludvig Völcker; Lowiza Svensson; [2023]
    Nyckelord :Splits; Liquidity; Signaling; Optimal trading range; Nasdaq Stockholm;

    Sammanfattning : This study examines whether stock splits still improve liquidity under current market conditions. To do so, we conduct three t-tests to examine changes in the bid-ask spread, turnover in relation to market capitalization, and Amivest Liquidity Ratio, around 64 share splits on Nasdaq Stockholm between 2013 and 2022, both for individual firms and on a general level.

  4. 3. Event categorisation and Machine-learning Techniques in Searches for Higgs Boson Pairs in the ATLAS Experiment at the LHC

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Milads Emadi; [2023]
    Nyckelord :Particle Physics; ATLAS; BDT; Boosted Decision Tree; Decision Tree; Optimization; Machine Learning; Analysis;

    Sammanfattning : This thesis investigates the pair production of Higgs bosons (di-Higgs events) at the ATLAS experiment in the Large Hadron Collider (LHC), focusing on the channel where one Higgs boson decays into two bottom quarks and the other decays into two tau leptons. The main objective was to determine whether introducing a split in the invariant mass of the decay products from the two Higgs bosons (the di-Higgs mass) and using this as an analysis variable improves the sensitivity of the Boosted Decision Tree (BDT) machine learning algorithm to the di-Higgs signal.

  5. 4. Simulations of the Tenuous Upper Atmospheres of Exoplanets

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Lucian Spitzner; [2023]
    Nyckelord :astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

    Sammanfattning : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. LÄS MER

  7. 5. A plant-based milk powder that functions as a substitution for regular milk powder

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Manon Scheffers; [2023]
    Nyckelord :spray drying; pant- based milk powder alternative; pea protein; food application; food engineering; Technology and Engineering;

    Sammanfattning : This project tested the potential of plant based milk powders to function as an animal-based milk powder by testing them on multiple characteristics. The powders were produced using spray drying techniques, obtained using formulations differentiating in protein amount, ratio of maltodextrin:sucrose and two different protein sources. LÄS MER
